AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The concealed post-verification redirect and wholesale query forwarding are concrete browser-side attack behavior, not package-aligned functionality. It does not execute during npm installation, but the shipped main artifact is malicious when opened.

Static reason

One or more suspicious static signals were detected.

Trigger

A user opens index.html and the Turnstile callback fires.

Impact

Potential phishing or leakage of URL-borne tokens to an undisclosed destination.

Mechanism

Obfuscated query-parameter forwarding and browser redirect.

Attack narrative

The package is a browser page masquerading as a security-verification screen. Once its Turnstile callback runs, obfuscated JavaScript constructs a hidden URL, copies every parameter from the current page URL, and calls browser location replacement. This redirects the visitor while forwarding query data to an undisclosed endpoint.

Decision evidence

public snapshot

AI called this Malicious at 94.0% confidence as Malware with low false-positive risk.

Evidence for block

Obfuscated callback builds a destination URL, copies query parameters, and replaces the browser location.
HTML presents a Cloudflare-style security-verification page and invokes the hidden callback after Turnstile events.
Manifest ships only this HTML page as the package main, with no legitimate package functionality.

Evidence against

No npm lifecycle scripts or Node install-time execution are declared.
No local file, environment, or child-process access is present.
